Carrie Underwood at the 55th Annual Grammy Awards at the Staples Center in L.A. (2/10)

Carrie Underwood and Taylor Swift are still fighting in that bitchy way that girls do, and avoided each other at Sunday's Grammys like Lindsay Lohan avoids employment. I know it's not exactly Biggie vs. Tupac, but I could easily see one of these chicks getting shot. From Us Weekly:

Taylor Swift never, ever wants to hang out with Carrie Underwood. A source tells Us Weekly that the country stars [avoided] each other at Sunday's 2013 Grammy Awards. According to the insider, Grammy execs were ordered to keep Swift, 23, and Underwood, 29, "from crossing paths" at the Feb. 10 show "since they hate each other!"

Says a Swift pal, "Taylor feels Carrie is always rude to her, so she steers clear of her."

Now we officially know that the empty suits at CBS are eunuchs. Seriously, if I was running the Grammys and I knew Taylor and Carrie hated each other this intensely, I'd cancel the awards part entirely and have those two fight in a kiddie pool full of hot oil, gummy bears, and sex toys on PPV. I don't know if it would break any buy rate records, but I'm sure there would be a hairy palms and blindness epidemic occurring in males, ages 12-80, and female college basketball coaches.
